Abstract
Hollow thermoplastic articles are produced by extrusion-blow moulding. Batches of parisons are produced from a continuously operating extruder which has at least one chamber to store the material and a reciprocating device to empty that chamber; the extruder action has two phases, whereby the chamber is at least partially filled in the one and is moved to the outlet of the extruder head in the other where it is expelled to form a parison; The volume of expelled material consists of the part held in the chamber and a part which is fed into the extruder head from the extruder(s) used, and at least one oart is exoanded under pressure in the blow mould of at least two tools and is then cooled. During at least a part of the (mould) filling stage the movement and/or speed of the device to empty the chamber is recorded by a central control unit and compare with nominal values; in the event of any set deviation at least one extruding parameter (e.g. shot volume, stroke of drive to empty the chamber, speed of expulsion from at least one chamber, extruder power etc.) is changed so that the preform from the extruder head is produced in the required vol. to the closest possible accuracy.
